Muse 5th Electrode not recognized

[encoded-evolution]

Hi @ChrisVeigl - I am using a 5th electrode with the Muse 2, but BrainBay does not recognize it. Using an alternate app, I can see that the electrode is producing signal - so the Muse and electrode are ok.

On the Brainflow website it appears that it should be supported. Is this something that I have to enable with a config string, or does this require an update to the code?

[ChrisVeigl]

yes - the config string can be sent to the device - maybe th 5th channel can be activated this way... but i never tried it because i have no device supportng this feature...

What is the syntax for that string? When I insert it and then apply config, the app crashes

hi,

I'm sorry i cant help here because i don't have access to the HW... I'd suggest to ask this question in the Brainflow forum or slack channel:

Here is the solution: in the config string field in the EEG Brainflow biosignal compatable settings, type

p50

that does the trick.

nice! - thanks :)
